B.3
C.4
D.5

Answer 1

$\textbf{\huge{ANSWER:}}$

Given:

Cost Price ( C.P. ) of toffee = Rs. 1

Profit % = 20%

Let the Profit in Rupees be = x

The formula for calculating the Profit % :

$Profit = \frac{Profit \: (in \: rupees)}{C.P.} \times 100$

Put the required values in the formula:

$20 = \frac{x}{1} \times 100 \\ \\ = > x = 2$

Now, the Profit = Rs. 2

Formula for Selling Price (S.P.) when the Profit is given:

S.P. = C.P. + Profit

=》 S.P. = 1 + 2

=》 $\textbf{S.P. = Rs. 3}$

$\textbf{(B) 3 is the answer}$
